Terrified

So I’m 18 weeks pregnant with my rainbow and I’ve been feeling her move a TON. But the past 5 or so days I haven’t felt her once and I’ve been having worse back pain than I usually do and I’ve been having some weird Round Ligament pain on my left side to the point I can’t even lay on that side and I just freaked myself the fuck out by googling late miscarriage symptoms

I called and left a message for my midwife I’m waiting for her to get back to me. I’m in tears right now I am so paranoid I’m having a missed miscarriage. I literally can’t stop crying . I just need to feel her move so I know I’m just being crazy. I still have to pee a lot and I was sick in the morning once last Wednesday but still... what do I do? Is it normal to all of a sudden not feel the baby moving around at all? I’m so scared 😢😢😢😢😢😢😢😢😢💔💔💔💔💔
